Title: Driving circuit of laser
Inventor: ARAI KATSUYUKI
IPC: H01S5/0683
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a driving circuit of laser in which emission intensity is not varied even if the mark rate is varied. SOLUTION: The driving circuit of laser comprises an extra capacitor C disposed on the anode side of the photodiode PD and suppressing variation in the output current level of a photodiode PD. Since variation in the output current level of the photodiode PD due to variation of mark rate is suppressed by the capacitor C, emission intensity of a laser diode LD is also suppressed. Essential purpose of the driving circuit of laser (compensation of variation in the emission intensity due to temperature characteristics) is not damaged because the capacitor C has no effect on the relatively long term variation, e.g. drift due to temperature characteristics.

Inventor: MURASE KAZUYOSHI
IPC: B29C53/54
Filed: 2001-03-02
Abstract: PROBLEM TO BE SOLVED: To solve the problem that since a repulsion force tending to return to an original shape is strongly operated when a thick tube material is rounded in a small diameter, a resistance of passing through a tube forming fixture is first increased so that a treating capability is lowered and the tube is second pulled by the resistance of passing through the fixture so that the tube is elongated, and hence its working accuracy is deteriorated and when the material has a foaming structure, the tube formed by forcibly rounding the material lowers a heat insulation performance due to collapse of the foaming structure of an inner peripheral surface. SOLUTION: A method for continuously manufacturing the tube 10 comprises the steps of bending the tube material of a long-sized state so that both ends 1a of the material 1 in a sheet width direction are butted, heating the butted parts, and heat welding its seam. The method further comprises the steps of forming a plurality of linear grooves Z continued in a longitudinal direction on one side surface of the material 1 for constituting an inner wall of the tube 10, and then bending the tube in a cylindrical state.
